Best phones for battery life at a glance

The sign of a strong battery is its mAh (milliamp hours) rating, which measures the storage capacity of a battery. The higher the mAh rating, the more charge a battery can hold and the longer it lasts. However, it’s important to remember that battery performance is also based on how well a handset can optimise power usage. Check out the phones with the biggest batteries below:

• Samsung Galaxy M62 (7000 mAh)
• Sony Experia 10 IV (5000 mAh)
• Motorola Moto G9 Power (6000 mAh)
• OnePlus 8T (4500mAh)
• Nokia XR20 (4630mAh)
• Samsung Galaxy S22 Ultra (5000 mAh)
• iPhone 13 Pro Max (4352mAh)
• Motorola Defy (2021) (5000mAh)

 

1- iPhone 13 Pro Max

Type	Li-Ion 4352 mAh, non-removable (16.75 Wh)
Charging	Fast charging (27W, unofficial rating), 50% in 30 min (advertised) USB Power Delivery 2.0 MagSafe wireless charging 15W Qi magnetic fast wireless charging 7.5W

The iPhone 13 Pro Max’s battery is first-rate. Apple’s flagship phone features a whopping 4352 mAh unit, estimated to last a day and a half (even with heavy use). It also supports fast charging and is purported to boost its battery by 50% in just 35 minutes. Not bad.

Great camera Good performance	Too big in size

 

2- iPhone 12 Pro Max 

Type	Li-Ion 3687 mAh, non-removable (14.13 Wh)
Charging	Fast charging 22W, 50% in 30 min (advertised) USB Power Delivery 2.0 MagSafe wireless charging 15W Qi magnetic fast wireless charging 7.5W

In second place, it’s the iPhone 12 Pro Max. The handset’s smaller 3687mAh battery offers over a day’s worth of charge (depending on usage). Like most premium Apple phones, the 12 Pro Max supports fast charging, increasing battery life by 50% in 30 minutes with a 20W (or higher) adapter.

3 - iPhone 13 

Type	Li-Ion 3240 mAh, non-removable (12.41 Wh)
Charging	Fast charging (23W, unofficial rating), 50% in 30 min (advertised) USB Power Delivery 2.0 MagSafe wireless charging 15W Qi magnetic fast wireless charging 7.5W

The iPhone 13 gets our bronze medal. Packed with a 3240mAh battery, the 13 may give you enough juice for more than a full day’s use. But at the very least, it should last from dusk till dawn. It also charges to 50% in 30 mins with a 20W adapter.

Strong battery Excellent cameras Good performance	Slow charging Poor selfie camera

 

4- Samsung Galaxy S22 Ultra 

Type	Li-Ion 5000 mAh, non-removable
Charging	Fast charging 45W USB Power Delivery 3.0 Fast Qi/PMA wireless charging 15W Reverse wireless charging 4.5W

Thanks to clever AI, the S22 Ultra can conserve battery when you’re not using it, so it should stay charged all day. The handset also supports fast charging and a Wireless Powershare function that lets you offload your battery to a friend in need. But despite having a humongous 5000mAh battery, Samsung’s internal 4nm chip isn’t quite as efficient as Apple’s Pro Max processor, leading to less talk time.

Pros:	Cons:
Good low light photography Great camera in general	Expensive

 

5- Samsung Galaxy A52

Type	Li-Po 4500 mAh, non-removable
Charging	Fast charging 25W, 50% in 30 min (advertised)

The Galaxy A52 weighs in with a sizeable 4,500mAh battery. Despite Samsung’s claims that it lasts two days, we’d argue it’s closer to one day. Nonetheless, it’s a decent battery, and if you find yourself short on power, fast-charging boosts you up by half in 30 minutes.

Pros:	Cons:
Great 5G option Plenty of upgrades Great display	Easy to scratch screen No HDR

 

6- Samsung Galaxy M62

Type	Li-Po 7000 mAh, non-removable
Charging	Fast charging 25W Reverse charging

  If you’re banking on a big battery, buy a Samsung Galaxy M62. The handset hoards a monster 7,000mAh battery which should provide two days’ worth of juice. It supports fast charging, too, so you can quickly plug in for a rapid revival.

Pros:	Cons:
Good design Strong chip Great camera performance	Not ready for 5G Heavy

 

What drains battery life?

• Temperature and age - Temperature and age are two triggers. The general rule is that 20% of your battery’s capacity is drained after every 1,000 charges. Batteries also work best at room temperature, so exposing your phone to hot or cold conditions isn’t wise.
• Screen brightness - Reducing brightness, refresh rates, and auto-lock times conserve battery life. Pro tip: use black wallpaper, and your screen will preserve power.  
• Active Apps - Your active apps make a big difference to battery life. For instance, a video or a games app will drain more battery than your calculator, as they require much more processing power. So, limiting your screen time is the best way to save juice.
• Passive Apps - It’s not just your open apps that deplete battery life. Apps that work in the background reduce your power in short bursts, too (like that pesky weather app). Although it doesn’t consume much battery in isolation, it all adds up if multiple apps are busy working behind the scenes.
• Connectivity - Connecting to things like location services swiftly eats into your battery. Even if you enable functions like Bluetooth and Wi-Fi but don’t use them, they still slowly drain your battery throughout the day. Unsurprisingly, connectivity to 4G or 5G services uses more battery power, especially in weak reception areas. We advise staying connected to WIFI while at home or work, so you don’t rely on phone signals for activities like streaming, browsing, and downloading.
• General use - All batteries die over time, and there’s not too much you can do to stop that. However, by limiting your apps and daily usage, your battery will keep on trucking for longer.
